Embedding

I'm having trouble downloading PDFs and viewing PDFs embeded in banking institution pages in Firefox.

When trying to download statements from Wells Fargo I get a setup.cgi file and when I try to view statements from Fifth Third Bank I get a Statement.jsp file.

I have no trouble downloading these files while on a PC.

I have Adobe Reader set as my default PDF reader and I also have the PDF for Firefox addon installed.

Any ideas what's going on?
